How to apply cotton bud fertilizer properly? Detailed explanation of fertilization methods and techniques
How to apply cotton bud fertilizer properly? Please give an introduction. After cotton squaring, it enters a period of simultaneous vegetative growth and reproductive growth, while still being dominated by vegetative growth. During this period, a framework must be built for high cotton yields. The supply of nutrients must not only meet the needs of the cotton plant's vegetative growth, but also prevent excessive or too heavy fertilization, which can cause cotton...

Fertilization Precautions and Key Planting Techniques for Shatang Mandarin
What should be noted when fertilizing Shatang mandarin? Please give guidance. During routine visits to rural areas, I found that quite a few farmers fertilize Shatang mandarin unreasonably. The following are listed for reference: One-sided and excessive application of nitrogen fertilizer: urea is the most commonly used in production. According to surveys, in recent years, mandarin orchards that applied urea alone as the fruit-fattening fertilizer accounted for about 40%, and it was applied arbitrarily, often resulting in excessive amounts; for example, applying more than 500 grams of urea per tree is not uncommon. One-sided and excessive application of nitrogen fertilizer causes the peel to thicken and become coarse, forming inferior thick-skinned large fruit; coloring is delayed, and a large number of green fruit appear; the flavor deteriorates and the juice rate declines, especially making the taste sour and astringent, unpalatable. Phosphorus and potassium fertilizers have an obvious effect in promoting fruit acidity reduction and sugar increase, and can promote the expansion of citrus fruit.

How to fertilize pear trees for good growth? A detailed guide to fertilization methods
How to fertilize pear trees for good growth? Please give an introduction. The life of a pear tree goes through several main growth stages: the young tree first-fruiting stage, the full-fruiting stage and the aging stage. At different growth stages, the fertilizer required differs. 1. Young tree first-fruiting stage: In early spring, a nitrogen-based fertilizer should be applied as a top dressing. After early summer, when new shoots stop growing, flower buds begin to differentiate and the fruit begins to swell, a phosphorus- and potassium-based fertilizer should be applied as a top dressing. After harvesting the fruit in autumn, a base fertilizer should be applied once more. 2. Full-fruiting stage: After bud break and before flowering, apply a nitrogen-based fertilizer once as a top dressing. From late June, when the fruit begins to swell, until just before harvest, root-zone top dressing (foliar spraying) should be carried out, and nitrogen, phosphorus and potassium fertilizers should be applied together during top dressing. After the pear fruit is harvested, the tree enters a recovery stage, and during this period the base fertilizer should be applied early. 3. Aging stage: After decades of growth and fruiting, the pear tree enters the aging stage, and four top dressings and one base fertilizer are applied throughout the year (an average of 250-500 kg of barnyard manure per tree each year).

How to Apply Top Dressing to Over-Summer Eggplants? Practical Fertilization Tips Shared
How to apply top dressing to over-summer eggplants? Here is an introduction to the methods you can refer to for top dressing over-summer eggplants: 1. Proper amount. Eggplants have the highest demand for nitrogen fertilizer, but in the high-temperature season, they should be fed small amounts more frequently. Each application of urea per 667 sq m should generally be kept within 30 kg. Because in the high-temperature season, urea transforms relatively quickly after being applied to the soil...
